NCT03283319

Brief Summary

The main purpose of this study is to assess the safety and ability of a Panblok H7 influenza vaccine adjuvanted with AS03 or MF59 to generate an immune response after 2 doses separated by 28 days. Three different antigen dose levels of Panblok H7 will be tested.

    Count of participants who experienced at least one of the following during at least one of the time frames specified: Solicited local reactions at the injection site: erythema/redness, induration/swelling, and pain

    Day 1-8, Day 29-36 (within 8 days of each vaccination, inclusive of the vaccination day)

  • Solicited Systemic Reactogenicity Symptoms for Participants Given Adjuvant AS03

    Count of participants who experienced at least one of the following during at least one of the time frames specified: Solicited systemic reactions include fever, myalgia (muscle pain), arthralgia (joint pain), fatigue, headache, nausea, vomiting, diarrhea, and chills.

    Day 1-8, Day 29-36 (within 8 days of each vaccination, inclusive of the vaccination day)

  • Solicited Local Reactogenicity Symptoms for Participants Given Adjuvant MF59

    Count of participants who experienced at least one of the following during at least one of the time frames specified: Solicited local reactions at the injection site: erythema/redness, induration/swelling, and pain

    Day 1-8, Day 29-36 (within 8 days of each vaccination, inclusive of the vaccination day)

  • Solicited Systemic Reactogenicity Symptoms for Participants Given Adjuvant MF59

    Count of participants who experienced at least one of the following during at least one of the time frames specified: Solicited systemic reactions include fever, myalgia (muscle pain), arthralgia (joint pain), fatigue, headache, nausea, vomiting, diarrhea, and chills.

    Day 1-8, Day 29-36 (within 8 days of each vaccination, inclusive of the vaccination day)

  • Seroprotection Based on Serum Hemagglutination-inhibition (HAI) Antibody Titers Against Guangdong Strain for Participants Given Adjuvant AS03

    The percentage of participants achieving seroprotection, defined as a serum HAI antibody titer \>= 1:40 against the H7 antigen (protein) contained in the vaccine. A higher HAI titer means a better immune response to the vaccine. A titer of 1:40 or greater is considered to be a sufficient amount of antibody to avoid influenza infection in half of exposed individuals.

    Day 50

  • Seroprotection Based on Serum Hemagglutination-inhibition (HAI) Antibody Titers Against Guangdong Strain for Participants Given Adjuvant MF59

    The percentage of participants achieving seroprotection, defined as a serum HAI antibody titer \>= 1:40 against the H7 antigen (protein) contained in the vaccine. A higher HAI titer means a better immune response to the vaccine. A titer of 1:40 or greater is considered to be a sufficient amount of antibody to avoid influenza infection in half of exposed individuals.

    Day 50

  • Seroprotection Based on Serum Hemagglutination-inhibition (HAI) Antibody Titers Against the Hong Kong Strain for Participants Given Adjuvant AS03

    The percentage of participants achieving seroprotection, defined as a serum HAI antibody titer \>= 1:40 against the H7 antigen (protein) contained in the vaccine. A higher HAI titer means a better immune response to the vaccine. A titer of 1:40 or greater is considered to be a sufficient amount of antibody to avoid influenza infection in half of exposed individuals.

    Day 50

  • Seroprotection Based on Serum Hemagglutination-inhibition (HAI) Antibody Titers Against the Hong Kong Strain for Participants Given Adjuvant MF59

    The percentage of participants achieving seroprotection, defined as a serum HAI antibody titer \>= 1:40 against the H7 antigen (protein) contained in the vaccine. A higher HAI titer means a better immune response to the vaccine. A titer of 1:40 or greater is considered to be a sufficient amount of antibody to avoid influenza infection in half of exposed individuals.

  • Women of childbearing potential are defined as postmenarcheal and premenopausal females capable of becoming pregnant. This does not include females who meet any of the following conditions: menopausal \>12 months, tubal ligation \>12 months, bilateral salpingo-oophorectomy, or hysterectomy.
  • Women of childbearing potential who refuse to use an acceptable method of birth control from screening to Day 50 (Visit 7) or, if sexually active with a male partner, who have not used a reliable birth control method during the 2 months prior to screening.
  • Adequate contraception is defined as a contraceptive method with a failure rate of less than 1% per year when used consistently and correctly and when applicable, in accordance with the product label, for example: abstinence from penile-vaginal intercourse; oral contraceptives, either combined or progestogen alone; injectable progestogen; implants of etonogestrel or levonorgestrel; estrogenic vaginal ring; percutaneous contraceptive patches; intrauterine device or intrauterine system; male partner sterilization at least 6 months prior to the female participant's Screening Visit, and this male is the sole partner for that participant (the information on the male partner's sterility can come from the site personnel's review of the participant medical records or interview with the participant on her medical history); male condom combined with a vaginal spermicide (foam, gel, film, cream, or suppository); male condom combined with a female diaphragm, either with or without a vaginal spermicide (foam, gel, film, cream, or suppository).
  • Have immunosuppression as a result of an underlying illness or treatment, or use of anticancer chemotherapy or radiation therapy (cytotoxic) within the preceding 36 months, or plans to receive immunosuppressive therapy/cytotoxic treatment during study participation.
  • Have an active neoplastic disease or a history of any hematologic malignancy. However, participants with superficial skin cancer who do not require intervention other than local excision are not excluded.
  • Have long-term use (≥14 consecutive days) of glucocorticoids including oral or parenteral prednisone or prednisone equivalent (\>20 mg total dose per day) or high-dose inhaled steroids (\>800 µg/day of beclomethasone dipropionate or equivalent) within 1 month prior to screening in this study. However, participants on low-dose inhaled steroids (≤800 µg/day of beclomethasone dipropionate or equivalent) or topical steroids are not excluded.
  • History of schizophrenia, bipolar disease, psychosis, or severe personality disorder.
  • History of hospitalization for psychiatric illness, attempted suicide, or having been deemed a danger to self or others within the past 10 years.
  • Have received immunoglobulin or other blood product (with the exception of Rho\[D\] immune globulin) within the 3 months prior to screening in this study.
  • Have received any live vaccines within 4 weeks or inactivated or recombinant protein vaccines within 2 weeks prior to screening in this study or plan to receive such vaccines (including seasonal influenza vaccines) from screening through 21 days following the second dose of the study vaccine (Screening Visit through Day 50).
  • Have an acute or chronic medical condition that, in the opinion of the site investigator, would render vaccination unsafe or would interfere with the evaluation of responses. This includes all PIMMCs such as Guillain Barré syndrome, narcolepsy, and current or history of autoimmune or chronic inflammatory disease.
  • Have an acute illness, including body temperature greater than 100.4°F, at screening, immediately prior to each vaccination or, per participant report, within 3 days prior to each vaccination in this study.
  • Received an experimental agent (vaccine, drug, biologic, device, blood product, or medication) within 1 month prior to screening in this study or expect to receive an experimental agent during the study period.
